During the installation of Autodesk Advance Concrete 2015 from 25 March 2014 15.0.1551.0, versions x64 9.0.30729.17 and x86 9.0.30729.17 of Microsoft VS 2008 redistributables are uninstalled.
Due to this, some software applications which use these components, might be affected.
For example when you run Advance Design 2014 after the installation of Advance Concrete 2015, you may encounter the following error: "The Snapin is stored in the register database but its loading failed"
The temporary solution for this problem is to manually install the Microsoft redistributables available at: http://www.microsoft.com/en-us/download/details.aspx?id=26368
Autodesk will create a new Advance Concrete 2015 setup which will correct this problem.
Note: If Microsoft VS 2008 redistributables, versions x64 9.0.30729.17 and x86 9.0.30729.17, are missing, some other software applications may be affected. Please check that the redistributables are installed on your computer.
